The fundamental problem is that autistic people, broadly speaking, don’t fit with neurotypical people. A high-functioning autistic person will eventually realize that, and realize just how utterly alone they are in life. They will realize that the people they think of as friends will never think of them as a friend.
First, I’m sorry for what you’ve been through. But from my personal experience, I know that I have three friends who have autism and/or ADHD. In each case, I did not know this until they told me. If I can’t even know who is autistic without them telling me, how can I treat them differently?
Now I understand that it is possible that some behaviours of mine could make my autistic friends uncomfortable, while not affecting my other friends. But if I am doing something like that, it is out of ignorance rather than malice, and I would of course adjust my behaviour if asked to.
So I don’t get why you think autistic people ‘don’t fit with neurotypical people’. I have friends who speak other languages, and autism is also, in a sense, speaking a different ‘body language’. With some effort, we should be able to improve communication.
The fact that you just aren’t understanding what I’m saying is demonstrating my point. You aren’t able to understand my point of view, and think that everything can just be solved by people working harder. It’s the same kind of belief that says that depressed and anxious people can be cured by just thinking happy thoughts and touching grass.
Can you be more specific? Why cannot autistic people fit in with others? Is it that others recognise them as being different and exclude them? Or is it that there are differences in the way we speak or behave that make you uncomfortable? And if it is the latter, what in particular should we change?
